Resident visa for parents in abu dhabi

I have been working here in Abu Dhabi for more than 6 months. Now I am thinking of bringing my parents to UAE. For sponsoring parents in Abu Dhabi, I understand that I need to obtain a residence visa for parents in Dubai. I came to know that I have to get the approval by a committee. How to get committee approval for residence visa for my elderly parents in UAE. I am the sole provider for my parents and I realize that for my parents visa in UAE I have to submit a sole provider proof. What is the Sole provider proof for my parents visa? Are there any new UAE residence visa rules for parents ?
